Hunting for the latest Menard County plat book? It's a printed atlas of landownership, usually by township, and it's handy for land around Oakford. In this county guide: what's in a plat book, where to find editions, and the free online map that stays current for land near Petersburg.
Getting started with the Menard County plat book
For a tract near Oakford, a plat book is a privately published atlas, that map ownership across the countryside, usually township by township.
Getting to the right map
Your first stop is the Menard County Beacon site; it maps each assessed parcel in the county, Fancy Prairie included. For a home near Lake Petersburg, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. With a lot near Bobtown, save the parcel ID before closing the panel; every office in the county uses it to find the file.
Places you'll see on the map
Petersburg is the county seat, home to the main records offices. You'll also find Athens, Greenview, Oakford, and Tallula, where town lots give way to larger tracts. About 11,954 people call Menard County home (Census estimate, 2023) spread over some 314 square miles. The county was formed in 1839, so old deeds can run back a long way for land near Oakford.
Where to look for one
Not every county has a current edition, so ask at the courthouse, extension office or a local library near Fancy Prairie.
Backing up the map with records
When the details count, pull the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Athens only summarizes it. For acreage around Lake Petersburg, have ready the instrument number from the tax record so staff can find the deed fast.
Between editions
The Menard County Beacon site is updated more often than any atlas, across the county.
Why people still buy them
Buyers and seed dealers around Atterberry rely on them to see ownership across many tracts at once.
Neighboring parcel maps

Ground near Bobtown that runs to the line may be split in two county records, so look at the adjacent map as well. For land near Greenview, the Platbookmapper state page links every bordering county map across Illinois.

On site with the map

A word on accuracy
If you're looking near Lake Petersburg, listed acreage is a tax-roll number; just a licensed surveyor sets the real lines on the ground. Closer to Hubly, records update in batches, so a deed recorded last month may not show yet.
Not the same thing
On ground around Lake Petersburg, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the county Recorder of Deeds (in many counties the County Clerk and Recorder) is a legal document, while the atlas is a reference.
Sections, lots and bearings
Illinois is laid out under the Public Land Survey System, so rural legal descriptions near Oakford cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Hubly vary in size. Write down the legal description for the tract near Hubly for any title or survey request.
